The Soldano SLO Pedal Custom Black Limited Edition is an overdrive pedal whose name spells out "SUPER LEAD OVERDRIVE"1. It is a limited edition version of the standard SLO Pedal, finished in the Soldano look drawn from the company's Super Lead Overdrive amplifier1. The pedal weighs 1 lbs.1.
The SLO Pedal carries the "SUPER LEAD OVERDRIVE" name from Soldano's amp lineage, and it works as an overdrive pedal1. The Custom Black Limited Edition weighs in at 1 lbs., a useful figure to know before it goes on a pedalboard1.
Soldano's product page listed the Custom Black Limited Edition as of 27 May 20261.
The controls
Soldano describes the pedal's front panel as boasting the same controls for Gain, Volume, Presence, and a three-band EQ as the 100-watt tube amp1. The maker's rundown of each control:
| Control | What it does |
|---|---|
| Presence | Filters the output's high end |
| Volume | Controls the total output volume |
| Deep switch | Adjusts the overall output low-end punch |
| EQ Section | Classic Soldano three band EQ; adjusting each knob clockwise increases the output of the relative frequency ranges |
The Deep switch is the kind of extra control an amp-style circuit makes possible: rather than a fixed voicing, it lets you set how much low-end punch comes out of the pedal overall, which matters when you are driving an amp that is already working hard1.
Power
The pedal runs on 9V DC with center pin negative polarity and draws approximately 32mA at 9V1. Soldano's warning is explicit: to avoid damage to the pedal, do not exceed 9V DC, do not use center pin positive adapters, and do not use AC power1. At roughly 32mA it is within reach of most standard pedalboard supplies, but it is worth checking the current rating on a shared output before daisy chaining.
Where it came from

Questions
What polarity does the Soldano SLO Pedal use?
The pedal uses a center pin negative power supply at 9V DC. Soldano warns against using center pin positive adapters, and against using AC power, either of which can damage the pedal. It draws approximately 32mA at 9V, so a standard 9V supply with enough current headroom will run it.
Does the Soldano SLO Pedal run on a battery?
The maker's product page does not list battery operation for the pedal. It specifies a 9V DC center pin negative supply drawing approximately 32mA, and warns against exceeding 9V DC, using center pin positive adapters, or using AC power.
How big is the Soldano SLO Pedal?
Soldano lists the pedal at 2.6 inches wide, 4.5 inches deep, and 2.25 inches high, with a weight of 1 pound. That is a compact footprint by stompbox standards, so it fits a crowded pedalboard without much trouble.
What is different about the Custom Black edition?
The Custom Black is a limited edition version of the SLO Pedal, carrying the iconic Soldano look inspired by the Super Lead Overdrive (SLO-100) amplifier in a black finish. The circuit and control set are those of the standard SLO Pedal, with the same Gain, Volume, Presence, three-band EQ, and Deep switch.
How long is the warranty on the Soldano SLO Pedal?
Soldano covers the pedal with a limited 5-year warranty, according to the maker's product page for the Custom Black Limited Edition.
